TUBE-CLIP.

Specification of Letters Patent.

Patented.Feb. 20, 1906.

Application filed May 16,1905. Serial No. 260,718.

To (ti/Z whom it may concern.-

Be it known that I, FnEnERIoK A. BEL- LAMY, a citizen of Great Britain, residing at London, England, have invented a new and useful Tube-Clip, of which the following is a specification.

My invention relates to clips for securing tubes of flexible or compressible material, such as rubber; to other tubes. or similar structures (if-harder material, such as iron or other metallicpipe. It may be used in any instance where it is desired to make connection between a flexible tube and aninflexible tube for carrying fluid of any kind.

The clip is simple, produced from standard commercial material, easy and ecoi'iomical to manufacture, and is very efficient, affording a means for very'tightly clamping the flexi ble tube, and one that is not liable to accidental disengagement.

.llxemplifying structures embodying my invention will be fully described in connection with the accompanying drawings, in which Figure 1 is a plan view of the body of the clip in a partially-mmpleted condition; Fig. 2, a side view of the completed clip of the structure of Fig. 1; Fig. 3, an end view of Fig. 3; Fig. 4, a side view of the clip clamped in place on a hose or flexible tube; Fig. 5, a plan view of a modified form of the clip in a partially-complcted condition, and Fig. 6 is a perspective View of the clip shown in Fig. 5 in a further completed condition.

Referring toFig. 1, a designates the clip as a whole as it is formed, preferably, by stamping from sheet metal (iron, steel, or,other material) of suitable thickness. The general, shape of the unassembled body is a long rectangular strip. Near one end of the body is a wider portion affording room in which to provide an'aperture I), which may be of vari able length, but must have a width at least equal to that of the majorportion of the body. Approximateto each end of the body is provided a hole (2.

The body having been produced in the shape indicated, it is assembled or completed by inserting the end of the longer straight portion of the body through the aperture f) and coiling the body so that it will remain in the approximate shape shown in Fig. 3. The figure shows for purposes of illustration the convolutions of the body slightly sqjiarated one from theothcr; but as actually manufactured they may be made to lie perfectly close to each other, forming a very compact structure. The bolt (1 is m sorted through the holes 0, and a thumb nut is screwedonto the bolt, thereby serving to bring the ends of the body together, as desired. q

The method of attaching the clip is obvious, but will be briefly described. As seen -.in Fig. 4,1 represents, a pipe or tube of compare tively hard. substance over which a flexible tube 0, such as a rubber pipe sufficiently large to be slip )ed or forced over the tube f is placed, the clip a having first been placed over one end of either tube. The clip is then placed in position near one end of the rubber tube, and its ends are drawn together by means of the thumb-nut, thereby securely binding the flexible tube to the other tube.

The clip is preferably made of spring netal, so that after use it may be used again and again, as by unscrewing the nut it will naturally assume its open position; but this is not essential.

Another form of construction is shown in Fig. 5, in which the main portion a of the body is considerably Wider than the ends inwhich are punched the holes a. Thecli is completed in a similar manner to the ot ier, as will be understood from Fig. 6, in which the clip is shown partially coiled.

If desired, the ends of the body may be crilnped or corrugated longitudinally (g, Fig. 1) in any suitable manner familiar to sheetmetal workers for imparting stiffness thereto. Preferably the clip is made long enough to pass twice around the tube which. is intended to be gripped, affording means for obtaining a great deal of constrictive force and. securely clamping the tube atall points without any break. The form and proportions of the clip may be widely varied to meet vary ing conditions.

. WVhat I claim is 1. A flat metallic strip having a widened portion near one end and a short aperture in said widened portion, said strip being formed into a constrictive clamp by passing one end of the strip through said aperture and ceiling the stripso that one portion of the coil liesoutside an inner portion thereof.

2. A flat metallic strip having a widened portion near one end and a short aperture in said widened portion, said strip being formed into a constrictive clamp by passing one end of the strip through said aperture and ceiling the strip so that one portion of the .coil lies outside an inner portion thereof, and also havin a short part of each end of said strip turne out at a right angle to the rest of the clip and perforated to accommodate a bolt for tightening the clip by means of'a nut or the like. v

3. A tube-clip consisting of a coiled metallic strip so formed that a single coil o f uniform Width encircles the tube to be clamped and a portion of said strip passes through an aperture thereof and encircles the first coil mentioned and ha'ving bent portions of said strip adapted to receive a locking device such as a bolt and nut.

4. A tubec1ip consisting of a coiled metal- 7 lie stri so formed that a single coil encircles the tu e to be clamped and a portion of said strip passes through an aperture thereof end I encircles the first coil mentioned, end having bent portions of said strip adapted to receive a locking device such as a bolt and mi 5. A tube-clip consisting of e, coiled instant lic strip so formed that a single coil encircles and contacts With the tube to be clamped and a portion of said strip passes thrcu 'h an aperture therein and encircles the coil' .rst men-- tioned.

In testimony whereof I have aftixed my signature in the presence of two Witnesses.
